Problems solved by technology

For traditional textile yarns, when the twist coefficient is less than the limit, proper twisting can increase the yarn strength, while for high-performance fibers, twisting will make the fibers in the yarn be arranged in a curved shape , affect the performance of the yarn, and may also cause damage to the fibers in the yarn

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment, the technical solution of the present invention is described in detail:

[0021] refer to figure 1 , The yarn rewinding device suitable for the inner-drawn yarn bobbin disclosed in the present invention mainly includes an arc-shaped support rod 101 , a rotating support 102 , a main shaft 103 , a bearing seat 104 , and a mounting support 105 .

[0022] figure 2 It is a side view of the disclosed yarn rewinding device.

[0023] refer to figure 2 , the mounting support 105 provides mounting holes for each component in the device. The side of the mounting support 105 is in an inverted L shape. For connection, the side of the mounting support 105 is provided with four mounting holes, which provide mounting holes for the bearing blocks 104 on the left and right sides.

[0024] The bearing seat 104 is used to install and fix the main shaft 103 to reduce the friction generated during the rotation of t...

Abstract

The invention discloses a yarn reversing device suitable for inner drawn bobbins. The device comprises a mounting support, two groups of inner supports, a main shaft and a bearing seat, wherein the mounting support provides mounting hole sites for components in the device; the inner supports clamp the bobbins in various shapes from the inner sides of the bobbins so as to ensure that the bobbins do not slide relatively in a rotating process of reverse winding; the two groups of inner supports are arranged on the main shaft which serves as a rotating shaft of the whole device; and the main shaft is installed and fixed on the bearing seat, so that friction produced in the rotating process of the main shaft is reduced, and the main shaft is connected with the mounting support together. By virtue of the device, the twisting phenomenon produced in the yarn reversing process of the inner drawn bobbins can be avoided, yarns can be uniformly guided away the bobbins without curling, and the quality of the yarns in the yarn reversing process is ensured.

Description

technical field [0001] The invention relates to a yarn rewinding device, more specifically, to a yarn rewinding device suitable for an inner-drawn yarn bobbin. Background technique [0002] The traditional yarn rewinding equipment and its supporting creels are only suitable for yarn bobbins with inner paper tubes, and when performing yarn rewinding of inner-drawn yarn bobbins, the yarn is usually drawn away from the inside of the yarn bobbin, and the yarn is in the Twisting occurs during the extraction process. For traditional textile yarns, when the twist coefficient is less than the limit, proper twisting can increase the yarn strength, while for high-performance fibers, twisting will make the fibers in the yarn be arranged in a curved shape , affect the performance of the yarn, and may also cause damage to the fibers in the yarn. Contents of the invention [0003] Aiming at the above-mentioned problem of twisting in the yarn rewinding process of the inner-drawing bobb...
